Phil:

Probably the central question needing answering is how many of these are you going to clean per month, and how fast do you need them cleaned up?

My initial reaction is that if you are going to clean less than one per business day, and do not need them cleaned immediately, I would seriously consider finding an old plating house that still used vapor degreasing... if such a thing still exists.

There are many many ways to clean, and it all comes down to the big three tradeoffs,
Good
Fast
Cheap

Pick two...

We have a large aluminum casting
Good afternoon,



We have a large aluminum casting (35 inches long by 10 inches wide by 10
inches high and weighs about 75 pounds) that forms the outer enclosure
of a finished product. After full assembly this unit it filled with
dielectric oil. For units which require repair after failure, we want
to clean out the old oil and any residue from the failure or from
machine shop rework. We would like a system that does not drain into
the local sewer or waste water system. Where this unit is used at 180kV
we need to get all the conductive schmoutz out. What are recommended
cleaning methods? Is there a MIL or NASA spec for cleaning large parts
like this?



I know that a final wash with DI water is probably the best, but what
would cut the oil best and what method of application?
